QHY367CThe QHY367C uses a full frame (35mm format) 36 Megapixel Sony IMX094 Exmor CMOS Sensor. Pixel size is 4.88um. This is the same sensor used in the Nikon D810A camera. At the lowest gain the readout noise is still only 3.2e-. At unity gain the readout noise is 2.4 e-. At high gain, 1.8e-. The Dynamic range is 1:17000, > 14 stops.

QHY128CQHY128C uses a full frame (35mm format) 24 Megapixel Sony IMX128 ExmorCMOS Sensor. Pixel size is 5.97um. This is the same sensor used in the Nikon D600, D660 and D750 as well as the popular Sony RX1 camera. At lowest gain the readout noise is still only 4e-. At unity gain the readout noise is 2.7e-. At high gain, 1.8e-. The Dynamic range is 1:17000, >14 stops.


Unique Thermal Noise Reduction TechnologyIn addition to standard 2-stage Thermoelectric Cooling, these cameras (as well as all QHYCCD COLDMOS cameras) employ a unique QHYCCD noise control technology that reduces the thermal noise of the cmos sensor. This technology is unique to QHYCCD cameras and reduces thermal noise to levels lower than can be achieved by competing cameras.

Zero Amplifier GlowThe QHYCCD128C and QHY367C have the rare capability of taking long duration exposures with zero amplifier glow, making them eminently suitable for deep space imaging as well as planetary imaging.

128MB DDRII Image BufferThe QHYCCD128C and QHY367C both have a 128MB DDRII image buffer. This frame buffer avoids the risk of frame loss and assures the integrity of the data when transferred over a busy USB 3.0 port or a slower USB 2.0 port.


True RAW Image OutputConsumer cameras often offer “RAW” image output, but users often find that the data is often not 100% raw. Traces of noise reduction and hot pixel removal are often present. In the QHY implementation, however, the data is truly the original signal, maintaining maximum flexibility for astronomical image processing.

Anti-Dew TechnologyWith years of experience producing cooled cameras designs, QHYCCD has fully implemented anti-dew technology for both the CMOS surface glass and the optical window. The cameras have a heating board for the optical window to prevent dew and a silicon gel tube socket design for control of moisture within the CMOS chamber.

AR+AR optic widnowIn order to avoid halos around the bright stars the optical window is AR+AR coated rather than the common IR cut coating common for color cameras. An IR cut filter is used to limit the wavelengths recorded to visible light, or it can be removed for more sensitivity to longer wavelengths and NIR.
